Malnutrition is highly prevalent in inflammatory bowel disease (IBD) patients and disproportionately affects those admitted to hospital. Malnutrition is a risk factor for many complications in IBD, including prolonged hospitalization, infection, greater need for surgery, development of venous thromboembolism, post-operative complications, and mortality. Early screening for malnutrition and prompt nutrition intervention if indicated has been shown to prevent or mitigate many of these outlined risk factors. There are many causes of malnutrition in IBD including reduced oral food intake, medications, active inflammation, and prior surgical resections. Hospitalization can further compound pre-existing malnutrition through inappropriate diet restrictions, nil per os (NPO) for endoscopy and imaging, or partial bowel obstruction, resulting in “post-hospital syndrome” after discharge and readmission. The aim of this article is to inform clinicians of the prevalence and consequences of malnutrition in IBD, as well as available screening and assessment tools for diagnosis, and to offer an organized approach to the nutritional care of hospitalized adult IBD patients.

BACKGROUND:Severe acute respiratory syndrome coronavirus 2, the virus responsible for Coronavirus Disease 2019 (COVID-19), has infected more than 8 million people worldwide and placed massive strains on healthcare systems around the world. Although classically causing cough, fever, and shortness of breath, increasing evidence suggests that manifestations of COVID-19 can be more subtle or masquerade as other clinical entities. CASE REPORT:A 48-year-old man with hypertension and type 2 diabetes mellitus presented to the Emergency Department with acute-onset pleuritic chest pain that had developed 1 day earlier and was found to be hypoxemic, requiring supplemental oxygen. He was admitted under the internal medicine service and underwent an extensive workup for his chest pain and hypoxemia, including a negative computed tomography scan with pulmonary embolism protocol, negative nuclear medicine ventilation/perfusion scan, normal electrocardiogram, and normal echocardiography. In the end, he was diagnosed with viral pleuritis as the diagnosis of exclusion. Our patient subsequently developed a fever and shortness of breath and his nasopharyngeal swab performed on admission to hospital returned positive for COVID-19. The patient’s pleuritic pain and oxygen requirements improved with supportive management over the next several days. CONCLUSIONS:I report a patient who experienced pleuritic chest pain from viral pleurisy that was the initial manifestation of COVID-19 which, to the best of my knowledge, has not yet been reported in the literature. This case report further emphasizes that COVID-19 may present with atypical symptoms. It is crucial to be aware of these atypical presentations of COVID-19 so that patients are appropriately identified, isolated, and treated, while protecting health care workers from exposure.
